Abstract: A deployment system for deploying a polymer grout system includes a first conduit line for conveying an isocyanate component, a second conduit line for conveying an organic polyol component, and a mixer for mixing the isocyanate component and the organic polyol component to form an expandable polymer grout system that is deployed to a target location associated with a wellbore. The deployment system can include a tailpipe and/or bridge plug for directing the expandable polymer grout system to the target location. The disclosure also includes methods of using the foregoing deployment system.

Abstract: A method for creating an expandable polymer grout plug within or through a wellbore includes providing an expandable polymer grout system to a target location within or through the wellbore, wherein the expandable polymer grout system comprises: (i) an isocyanate component comprising one or more isocyanate compounds; and (ii) an organic polyol component comprising one or more organic polyol compounds; in the presence of (iii) one or more blowing agents; combining the foregoing components of the expandable polymer grout system to facilitate the polymerization reaction to form the expandable polymer grout plug at the target location; and allowing the expandable polymer grout plug to cure at the target location.

Abstract: A method of deploying an expandable composition in a cement top job in a well system includes identifying evidence of actual or potential gas migration within an annulus cement of the well system. Once the evidence of gas migration is identified, a first component and a second component are mixed in a mixer to form the expandable composition and the expandable composition is pumped from the mixer through a conduit to a top of cement of the annulus cement. The expandable composition expands to form an expanded composition that seals the annulus above the top of cement of the annulus cement. Cement can be added onto the expanded composition.
